Photo comparison: Brilliant Ideal Cut v.s. Firey Ideal Cut??

[movesale03]

Hello.

I was just curious if anyone has a photo of Brilliant Ideal Cut.

My understanding is that most branded "Hearts & Arrow" are Firey Ideal Cut, correct?

Then when I want to compare a Brilliant Ideal Cut and a Firey Ideal Cut, where can I go?

Would very much appreciate if anyone is kind enough to post the photo of the Brilliant Ideal Cut.

(

would love to see both BIC and FIC side by side, but maybe that is too much asking...)

Thank you!!

Hello.

I don't think so... actually, you might want to run a search for "FIC" - a few posters were looking out for these without much success.

The jury seems to still be out on what difference is if any between these.

Some recent posts by Garry and David Atlas ("Oldminer") brought up the issue again.

To make things worse, I kind of doubt the difference between a fiery and a brilliant stone can be photographed. Perhaps each diamond can be shown either or depending on lighting conditions and photographic technique. About the same is true in nature: once the cut can deliver god light return, the type of lighting available may yield more of less "fire". The slight differences of character that make some diamonds better looking in one type of lighting or another might be the ultimate test of photographic skill. I have yet to see that display materialize

Not that I wouldn't like to see it...

Just my 0.2.

Move,

I think Garry Holloway of BIC, TIC & FIC fame may have developed that typology initially by studying hypothetically excellent performance. At the same time, and while he''ll stand by that layout of options, he''ll readily admit your standard FIC now appears about once in 2000 diamonds...definitely not your standard hearts & arrows option. Not sure how many of them would be BICs, but probably many are TICs, also conforming to AGS0, past and future...especially for the options frequently recommended here.

Hello.
gh responses in blue
I was just curious if anyone has a photo of Brilliant Ideal Cut. i will take some shots of a stone that I have

My understanding is that most branded ''Hearts & Arrow'' are Firey Ideal Cut, correct? wrong - 99% are TIC

Then when I want to compare a Brilliant Ideal Cut and a Firey Ideal Cut, where can I go? very hard - you can hunt on Cut Quality for stones with known prportions - look for stones with lower crown angles and good HCA (BIC) or steeper crowns and good HCA scores - very very rare

Would very much appreciate if anyone is kind enough to post the photo of the Brilliant Ideal Cut.

I think I have a same weight TIC to put next to the FIC

Thank you!!

valeria101, Regular Guy, and Gary,

Thank you very much for your comments and suggestions. (in shuch a short time)

Gary, and I am looking forward to see the photo. Thank you for your offer!!

I realized that my question was not worded well.

Correct me if I am wrong, I was under impression that
having a well defined arrow pattern (regardless of the brand) produces more firely effect,
and as Gary''s article (and his tutorial) mentions that the Briiliant Ideac cut produces more light return.

Now, while browsing through numbers of vendors online, lots of them have
nice "Firely cut/well defined arrow pattern" diamonds, however,
I was not successful in finding a GOOD Brilliant Cut diamond.

As my taste is more for the "Light Return,"
I was hoping to see the difference in these two types of cut visually.

And, the only way to search for Brilliant cut Diamond is to just keep looking at the Proportion Numbers?
Or, would there by any vendor specifically marketing "Brilliant cut" diamond?

Lastly, how would the Brilliant cut Diamond look under the normal sun light/room light?


Again, Thank you very much!!

in office fluoro lighting firey ideals have visibly more fire and BIC''s are simply brighter all over.
No diamonds look good insunlight

Ohhh, I seee. Thank you again for your comment Garry. (sorry, I missed second "r" in the previous message)

Diamond is very interesting subject to learn!!

 

[Garry H (Cut Nut)]

The top stone is a FIC
The bottom a BIC

Dont ask me the exact proportions cause i dont have time
but an educated guess is 37ish crown angle for the FIC and around 4 pavilion.
32-33 crown and around 41.1 pavilion for the BIC

The BIC has a bigger spread
The FIC has a small spread but a huge amount of sticking out effect of a ring when set. (Dare I say - a little like an overly well endowed lady)
The FIC also appears to have 1/2 as many facets extra as the BIC

Garry
what''s the table % on that FIC ? 53% ? and the crown height? is it leaking light under the table?

 

[Garry H (Cut Nut)]

memory is either 50 or 53%
it also has a thick girdle and that is causing some leakage near the outer perimiter of the table - but otherwise its light return is remarkably strong for a stone with this steep crown.

Everyone who sees it can not help notice how much fire it has.

Garry, thanks so much for these pics.........

why dont you put some of your experimental pics up?

BTW what do people think of the realistic photo''s?
Are they attractive and desirable looking shots?
(they have absolutely no backlight - you can see the leakage ideal-scope areas = black in the real photo''s

Cool.

A bit flat and somewhat cold. No idea how you could get some perspective in there and keep any light from the pavilion... not to mention the face-up alignment.


Given the black background, lickeage and contrast (what the arrows do) look the same in the black&white photos. Perhaps using a colored background would let lickeage show in a different color without tinting everything else too much ?

Gary,

Are those actual photos on the left hand side or are they computer generated? If they are actual photos then I don''t care for them much as I find them very flat and lifeless. They don''t look anything like they would to the eye and I think they are doing a disservice to your beautiful stones. When ever I have seen these type of photos I have been making an apparently erroneous assumption that they were computer generated.

Garry, Thank you very much for the lovely BIC and FIC photos!

Been away for a while and I feel guilty not being able to reply sooner.

These photos sure help me learn more about diamond!!

THANK YOU!!!

p.s. when I get my new digital camera (hopefully soon), I will try to take a Macro photo of my diamond.

Garry those are probably some of the better cut BIC and FIC stones out there right? Hard to find!!

move, I had a BIC and I ended up getting rid of it because it bothered me, it was always white brilliant looking with not enough colored sparkles inside. I ended up going for a TIC with a good blend of both white brilliance AND fire and I love the combination more than giving up one for the other. Just an FYI, with a TIC and a good blend you get the best of both worlds. My stone still faces up white brilliant, it just has more going on INSIDE of it too. and it looks so much better in more lighting situations than my old BIC.

Just my experience.
